Reactions of nitric oxide are often treated as if they were of this order. This is the highest power of volume in the Redlich-Kwong equation of state. Apery's constant is the value of the Riemann zeta function at this number. According to the Debye [duh-BYE] model, specific heat is proportional to this power of the temperature. The asteroid denoted by this number is Juno. Algebraic equations of this order may be solved using the Tartaglia-Cardano formula. Monocots have a multiple of this number of petals. Platyhelminthes is the most primitive phylum to contain a mesoderm and, therefore, to possess this many germ layers. For 10 points, give this number that is also the number of nitrogen dioxide substituents on TNT.
